Afghan Insurgents Still Finding New Ways To Disguise Roadside Bombs

U.S. soldiers carry a comrade injured by an improvised explosive device, or IED, in Logar province, south of Kabul, on Oct. 13. Roadside bombs are one of the biggest threats facing U.S. and Afghan troops, and insurgents keeping finding inventive ways to disguise them.

On the morning of Oct. 18, an Afghan National Army patrol received a tip that a body bag with human remains was lying near a graveyard in Pul-e Alam, the capital of Logar province.

The Afghans went to investigate and found a blood-covered body bag with what looked like a pair of pants sticking out of it.

According to U.S. troops, as the Afghan forces were investigating the scene, they heard a cellphone ring. It turned out to be a detonator for a bomb placed in a tree near the bag.

But it was a dud and didn't explode –- otherwise it could have had deadly results.

The Afghan army immediately backed away from the scene and then re-approached with vehicles armed with radio-jamming equipment. This prevented any further radio-controlled bombs from being detonated.

They proceeded to investigate the site and found that the body bag contained two 18-liter jugs filled with explosive material connected to a cellphone detonator. They found several other similar devices buried around the scene.

The Afghan troops successfully cleared the site.

This scene highlights how insurgents continue to adapt and experiment with new tactics and approaches. The roadside bombs come in all shapes and sizes, and have grown more sophisticated and more lethal.

There are IEDs set off by trip wires, pressure plates (similar to the way landmines work), timers and, as in this case, by cellphones.

Insurgents hide them in culverts, bury them in roads and sometimes place them in walls or inside dead animals. In some cases, they are even put inside dead people.

Still, U.S. troops say that Afghan forces tend to have predictable patterns when they patrol, and insurgents are placing the bombs where Afghan soldiers regularly dismount their vehicles. This is one of the habits U.S. troops are trying to get Afghan forces to break.

The U.N. says that IEDs have killed more than 340 civilians this year and injured at least 600.
